MACHINE FOR FORMING AND SEANHNG SHEET iViETAL TUBES.

SPECIFICATION forming part of Letters Patent 150310395, dated January 20, 1.885.

Application filed May 15, 1884. (No model.)

To all whom it may concern.-

Be it known that LEDMUND JORDAN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Machine for Forming and Seaming Sheet- Metal Tubes, of which the following is aspecification.

My invention consists in a machine for forming and seaming sheet-metal tubes, and comprises the following: a graduated horn, a sleeve or former revolving around the horn, a carrying device for moving the tubes from where they are formed toward the discharge end ofthe horn, a device for bringing the edges of the seams evenly together, a device for putting the tubes into proper position on the horn to have the'seams closed, an adjustable jack to support the horn, a pressing device or force to close the seams, a device to strip the tubes off the horn after being formed and seamed, and a device to operate a feed-table, combined with other mechanism, fully described and claimed.

In the accompanying drawings similar letters of reference indicate corresponding parts throughout.

Figure 1 is a front elevation of my improved machine, showing its position after a tube has been formed around the horn. Fig. 2 is a front elevation of my improved machine after a tube has been formed on the horn and then moved under the force, showing the application of the force to the seam of the tube. Fig. 3 is an end elevation of Fig. 1, and Fig. 4 is an end elevation of Fig. 2. Fig. 5 is an end elevation, the opposite of Fig. 3. Fig. 6 represents a side view of a lever and cams to operate the gear-sector which rotates the sleeve and former. Fig. 7 is a side view of the cams and yoke which operate the carrier or slide and stripping-fingers, showing their form and relation to each other on the shaft. Fig. 8 is a side view of the cams and yoke to operate the force, showing their form and relative positions on the shaft. Fig. 9 is a side view of a longitudinal section of the sleeve carrying the former on a stud and the gear-wheel and clutch-pin which engage and rotate the sleeve, showing their relative positions on the stud.

10 is a side view of the sleeve and gearwheel and their position on the stud, the broken lines indicating a portion of the gear-wheel removed, showing the clutch-pin, groove,stop, and spring. Fig. 11 represents aside view of the cam and lever which operate ameehanical doctor to move the seams of the tubes into proper position on the horn to be closed by the force. It also shows a cross-section of the doctor, an end view of the force, and an end view of the seam or a section of the horn ready to receive the force. Fig. 12 is a front View of the cam, lever, and doctor, showing the general features of the same and the manner of adjusting the doctor to accommodate different sizes of tubes. Fig. 13 is an end View of the seam after it is closed by the force. Fig. 14 is a side view of the cams which operate the slide carrying the stripping fingers. These are placed in the yoke shown in Fig. 7. Fig; 15 is a side or top view of the cams which operate the lever for actuating the gear-sector, thereby rotating the sleeve and former. Fig. 16 is an end view of Fig. 14.. Fig. 17 is a side view of Fig. 15, showing the forms of the cams and their relative positions on the shaft. Fig. 18 represents a longitudinal section of the former, taken at line 9 y, Fig. 19, and a longitudinal side view of the graduated horn, in their relative positions. Fig. 19 is a cross-section of the graduated horn and former, taken at line z c, Fig. 18. Fig. 20 is an end View of the horn, showing the grooves in the same. Fig. 21 is a front view of the adj ustable supporting-jack which supports the end of the horn when the force is applied to the seam. Fig. 22 represents a vertical cross-section of the jack, taken at line mm, Fig. 21, and shows the crank an d cam which give the jack an intermittent vertical motion. Fig. 23 represents a plan view of the slide carrying and operating the stripping-fingers. Fig. 24 represents an end view of the slide-fingers, and also of the sliding cam which operates them, and which is shown by dotted lines. Fig. 25 is a cross-section of the fingers, sliding cam operating the fingers, and the cam-plates, taken at line ww, Fig. 23. Fig. 26 is a perspective view'of the sliding cam. Fig. 27' is a perspective view of the cap holding the sliding cams in place. Fig. 28 is a side view of asection of the fingers, showing the spring-joint in the same. Fig. 29 is a perspective view ofa guide for keeping the seam looked after the tube is formed on the small portion of the horn while it is being moved to the enlarged surface of the same, where the seam is closed. Fig. represents the vertical bar or slide that carries the adjustable forked stop against which the tube strikes when moved on the horn under the force to bring the edges evenly together before the seam is closed by the force. Fig. 31 is a side view of the same and of the adjustable forked stop. Fig. 32 is a top view of the adjustable forked stop. Fig. 33 is a longitudinal section of the lever operating the slide which carries the fingers, taken at line 1) c, Fig. 2, showing the slot for adjusting the throw of the slide. Fig. 34 is a side view of the cam on the end of the shaft which operates thejack and the adjustable stop, and Fig. 35 is an end View of the same. Fig. 36 is an end viewof a cam which actuates the levers and rock-shaft to operate the dividing feed-table.

.Fig. 37 represents a plan view of the machine with the top removed, taken at a line just above the main shaft.

F represents the frame, constructed of castiron, of suitable dimensions, set upon legs L or other supports.

H is a horn with different diameters,with a graduated surface from the smaller to the larger diameter. This horn is letinto the end ofa stud, Fig. 9, set into a hub or socket, h, cast in the frame. In the drawings this horn is shown cylindrical. It may be made in other shapes. The stud and horn are held in place by bolt 11, passing through the hub h and stud w, and tapped into the end of the horn. h h are longitudinal grooves in the horn, in which the ends of the stripping-fingers move.

h h are longitudinal grooves in the upper surface of the horn, in which are adjustable stop-grooves.

h is a horizontal groove in the upper surface of the horn to receive the seam of the tube. At the point on the horn opposite to the feedtable one end of this groove If is slightly cut away to accommodate the width of the tube to be formed. On the opposite shoulder of the groove a hook, h, is rigidly attached to the horn. The hooks on the edges of the metal from which the tubes are formed are inserted between the hook h and the surface of the horn, and thereby held while being formed. The part of the horn where the sheet metal is formed is of such diameter as to allow the hooks on the opposite ends of the metal to lap each other when formed around the horn and s is a former, (clearly shown in Fig. 19,) rig- 8o idly attached to the sleeve 8 at and fitted over the horn in such manner as to allow the metal to be formed around the horn inside the former.

8 represents a longitudinal slot in the former, one edge cut away to allow the operator to insert the sheet metal u nder the hook h*.

It is obvious that the constructionof this former may be changed to a pin held rigidly to the sleeve 8 and I claim either or any equiv- I alent former; but if a sleeve-former is preferred, it should be provided with longitudinal grooves s 8 similar to those in the horn, to accommodate the stripping-fingers.

s is a gear-sector pivoted in the frame at f, and meshed with gear-wheel 8".

8 is an adjustable connectingrod, and s a lever pivoted to the frame atf, and operated by cams s and s, rigidly attached to the main shaft 8 The cams, lever, connectingrod, and gear sector rotate the sleeve and former. The sleeve and gear-wheel make a complete revolution, and theformer then stands at rest, held by a stop-lever, f operated by a cam, a, on the main shaft, and a spring held in the frame,while the revolution of the gearwheel is reversed, until the clutch-pin is let into the groove in the sleeve, when the former is ready for a second operation.

a, Fig. 23, is a slide moving horizontally in the frame, and receives motion by means of connecting-rods, lever, and cams, as here inafter mentioned. It is depressed in the longitudinal center, and carries the strippingfingers, which will be fully described at a later point in this specification.

a represents an adjustable connecting-rod, attached to the lugs on the slide a at one end, and at the other to a lever, a", pivoted to an arm of the frame at f.

a is alongitud-inal slot in the lever a by means of which the throw ofthe slide a is regulated.

a is a rod connecting to lever a and the bell-crank a which is pivoted to the frame a is a rod connecting the b'ell-crank 0t and the vertically-moving cam-yoke a], so constructed as to move in the frame.

a and a are cams fixed rigidly on the main shaft 8.

a and a" are rolls fitted in the cam-yoke,

which work on the face of the cams. These l (i represents the doctor, consisting ofa plain several devices are provided toimpait a hori; zontal motion to the slide or carrier. On each side of the carrier are projecting ears or lugs, provided with a crossgroove at right angles to the slide, into which the projecting shanks on the fingers are fitted to impart a horizontal motion to the same.

c and represent the stripping-fingers, provided with projecting ends, which move in the grooves h h in the horn, The cam-plate c", Fig. 26, is placed over the projections on the fingers and the surface of the lugs or cars on the slide, and is fitted into a groove in the top plate.

0 represents a pin in the cam-plate.

0 is a slot in the cam-plate, and c is a camslot in the cam-plate.

0 represents a cap covering the sliding cam c. The fingers, sliding cam, and cap are all held in place by bolt 0.

0 0 are cross-slots provided in the projecting ends of the fingers to accommodate a horizontal motion of the fingers when in use. The angles of the cam-cap are provided with bolt-holes, and are rigidly bolted to an adjustable block sliding in the projecting ears of the slide.

c c are spring-joints in the fingers to impart elasticity to the same, thus preventing injury to the edges of the tubes while being moved on the horn. These may be omitted without interfering with the usefulness of my invention. The slide-fingers and cams move horizontally with the slide, and the fingers work in and out of the grooves in the horn by the sliding cam device already described. When a sheet of metal is formed on the horn, the slide carrying the fingers expanded moves forward at the time the gear-sector is traveling backward, while the former stands at rest until the pin 0 strikes a stationary stop on the frame. The slide continues its travel, thereby crowding the fingers into the grooves h h in the horn by the motion of the eamplate. \Vhen the travel of the slide is reversed, the projecting ends of the fingers c c embrace the end of the tube on the horn and carry it on to the enlarged surface of the horn under the force. At the extreme end of the throw pins n a in the levers n a move forward and strike the sliding cam-plate, reversing its position, and thereby expanding the strippingfingers.

d represents a stationary adj ustable guide fastened to the frame by a bolt. The flanged end is placed in close proximity to the horn over the locked seam, and the projecting end is located near the end of the former to keep the seam of the tube lockeduntil the tube is carried on to the enlarged surface of the horn. The circular depression dis provided to guide the seam into its proper place to be brought under the force. Any equivalent may be used without interfering with the usefulness of my invention.

sheet of metal with a projecting lip, as indicated in Fig. 12, the ends being attached to adjustable bars d and (1*, provided with a slot to adjust the same. The slotted ends of the bars are attached to a cross-bar, (P, which is rigidly attached to a circular lever, (l and pivoted to the frame at f.

The meeh anism herein described is actuated by a cam, (F, on the main shaft .9, working against the circular end of the lever, as indicated in Fig. 11. The doctor is so adjusted that the projecting lip strikes the locked seam of the tube and moves it into position to receive the force to close the seam. This is so timed as to operate immediately after the tube comes to a rest, as indicated in (F, Fig. 11.

9 represents an automatic adjustable forked stop with projecting ends, as indicated in Fig. 82. The stem is fitted into rod g, provided with a collar, 9, and attached to the frame by bearings and g". g/ is a vertical slide working in its bearings. Around the stem of the forked stop is a coiled spring to form an elastic stop. The projecting ends of the fork work in grooves h h in the horn, as illustrated in Fig. 20. The stop is provided to bring the edges of the tubes evenly together before the force is applied, and is moved vertically to allow the tubes to be stripped from the horn after the seam is closed by lever 9", one end of which is attached to collar and the other slotted end to eonnectingrod g, which connects with levers g pivoted atf. The projection on the end of the lever 9 works in the cam-groove in the side of cam 9 rigidly fixed on the main shaft 5. When the force is applied, this forked stop is raised by the mechanism just described, in order that the ends of the stripping-fingers 0 0", which work in the grooves in the horn, may strip the tube from the horn at the same time that another tubeis being carried by hooks c c from where it is formed to where it receives the force, and this same mechanism operates the supporting-jack g, which consists of a screw let into a movable slide, operated by a cam, g, which is rigidly fixed 011 shaft 9. On the opposite end of this shaft is a crank, 9 which is connected with a connecting-rod, g. g is a slide working in a sleeve. The jack is raised to support the horn immediately before the application of the force to the seam, and recedes immediately after to allow the tube to be stripped from the horn, as before mentioned. The jack and the mechanism immediately connected therewith are rigidly attached to the frame.

is a tongue to fit a groove in the frame. a a are two adjustable pins in the ends of le vers it a, attached rigidly to rock-shaft n, which has bearing in the frame. To this rock-shaftalever, a, is rigidly attached. The opposite end of the lever works on the face of a cam-wheel, and is actuated by a side cam, which actuates thepins n n, and causes them to strike against the end of sliding cam-plate 0, driving the same forward, and thereby expanding the stripping-fingers, so that they move forward to grasp a tube on the horn. This motion is so timed as to strike the sliding cam-plate immediately preceding the time when the slide reverses its travel to return for a tube formed over the horn, as before described.

m, Fig. 11, represents a vertically-moving force to close the locked seam; andit consists of a metallic force or die working in guides.

m represents the adjusting screw connecting the force with the cam-yoke cf, Fig. 8, which is operated vertically by cams m and m, rigidly fixed on the main shaft .9, working on rollers m and m in the cam-yoke, and imparting a vertical intermittent motion to the force m, so timed as to apply to a seam when the fingers are returning for a tube pp, Fig. 2, represent a dividing feed-table, which closes to receive a sheet from the operator, to be conducted under the hook on the horn immediately preceding the rotation of the former.

p 1) represent two connecting rods, one end of each connected by a bell-crank, 19 to each side of the dividing-table, and the upper ends rigidly fixed on a rock-shaft, f, on which one end ofa lever, p, Figs. 3 and 36, is rigidly fixed, the opposite end working on the face of cam p rigidly attached to the main shaft 8. The mechanism described opens the dividing-table immediately after the sheet is pushed under the hook on'the horn, allowing the former to form the sheet metal around the horn, and then closes to secureasecond sheet. These several mechanical movements are so timed and arranged as to work in unison.

R represents a short shaft having its bearings in the frame.

8 represents a roller pivoted to arm 8, which works as the face of an actuating-cam.

R represents a fast and a loose pulley on the shaft R. 011 the opposite end of this shaft is a small gear-wheel meshed with a larger gear-wheel, R, on the main shaft, which has its bearings in the frame.

The horn may be other than a true cylinder.

Operation: The sheets of metal, cut to the required size and having hooks turned on the ends to form a locked seam, are placed on the dividing feed-table with the upturned hook on the sheet in advance. The sheet is then conducted forward with the edge under the hook on the horn. At the time the former commences its rotation the feed-table opens, allowing the sheet to drop,when it is formed around the horn by the rotation of the former,

sleeve, when the former is ready to form another sheet around the horn. While the gear-sector is traveling backward the slide carrying the stripping-fingers extended moves forward, the projecting pin in the sliding cam striking the stationary stop and closing the fingers, which move into the grooves in the horn. When the travel of the slide and fingers is reversed, the projecting ends of the fingers are brought in contact with the edge of the tube, moving it to the graduated portion of thehorn,the locked seam being kept in place by the stationary guide in the frame, and the elastic stop brings the edges evenly together, when the tube remains at rest under the force through the action of the pins 12 n against the sliding cams, thereby extending the fingers outward from the horn, when the tube is in readiness to receive the force to close the locked seam. Preceding the application of the force the jack is brought under the horn to support it when the force is applied. After the application of the force the jack and the adjustable forked stop recede from the horn, allowing the tube to be stripped from it.

I claim all equivalents to accomplish the same ends, whether used horizontally, vertically, or otherwise.

I claim and desire to secure by Letters Patent of the United States 1.
